I feel like too many illnesses have the same symptoms.  If you have a runny nose, sore throat, headache, cough, sinus pressure, and/or a fever, you could have:  (a) the common cold, (b) COVID, (c) allergies, or (d) cancer.  The human body is like, "I don't know what to do about this, so I'm just gonna produce some mucus." #health
